Abstract: A system for transmitting a value via a pulse-width-modulated signal, comprises a transmitter and a receiver. The transmitter is configured for detecting the value and for outputting a pulse-width-modulated signal having a pulse width which represents the value or a range around the value. The receiver is configured for deriving the value or the range from the pulse-width-modulated signal, by evaluating the pulse width. The transmitter is furthermore configured to read back the emitted pulse-width-modulated signal and to check whether the value or the range can be derived from the emitted pulse-width-modulated signal, and, if the value or the range cannot be derived, to output an error signal to the receiver.

Abstract: A reinforcement device for reinforcing an electric bicycle frame at least in a region of a tube cutout of a bicycle frame tube which accommodates an energy storage. The reinforcement device includes a first reinforcement element which extends axially in the bicycle frame tube and/or extends at a certain angle to the bicycle frame tube, and at least one second reinforcement element which extends axially in the bicycle frame tube. The reinforcement device is installed in the bicycle frame tube.

Abstract: A tire, in particular cycle tire, with a device for generating rotation-dependent signals, in which the device is arranged in the tire or is connected to the tire and has a signal-generating element, which is held in a retaining element connected positively or non-positively to the tire body. The receiving element is arranged substantially on the outside of strengthening elements or reinforcing elements of the tire and the signal-generating element is held in the retaining element in such a way that the signal-generating element forms part of the outer surface of the tire or protrudes beyond the outer surface of the tire.

Abstract: The invention relates to a bicycle tire with high riding comfort. A damping rubber insert (3) made from a highly elastic rubber is arranged between the tire tread (2) and the tire carcass. Said damping rubber insert (3) has a material thickness of between 0.2 and 2 mm, and the carcass insert ends (10) extend to a maximum of the lateral edge areas of the tire tread (2).

Abstract: Tyre, in particular cycle tyre, with a device for generating rotation-dependent signals, a method for producing said tyre and a system for controlling a cycle drive with such a tyre. Tyre, in particular cycle tyre, with a device for generating rotation-dependent signals, in which the device is arranged in the tyre (1, 3) or is connected to the tyre and has a signal-generating element (6, 14), which is held in a retaining element connected positively or non-positively to the tyre body, wherein the receiving element is arranged substantially on the outside of strengthening elements or reinforcing elements of the tyre and the signal-generating element is held in the retaining element in such a way that the signal-generating element forms part of the outer surface of the tyre or protrudes beyond the outer surface of the tyre.

Abstract: The invention relates to a bicycle tyre. A puncture-resistant fibre layer (4) having a plurality of polymer, parallel running tyre reinforcing elements (12) is arranged between the tyre tread (2) and the tyre carcass. Said reinforcing elements (12) are arranged at an angle of between approximately 80 and 110 degrees with respect to the peripheral direction (13) of the bicycle tyre.
